I've had this issue too. I agree totally sounds like a bad gas issue.
Having said that:
You can test very quickly to see if the engine kicks with some starter fluid and then probably stalls. The you know it's fuel related
I would definitely change/check the fuel filter. If you have a clear...
As a rule the cylinder cast most forward on a Chrysler is number one. The 383 you know is on the front driver side.
If you have a vacuum advance canister on your distributor pull the hose off the canister plug it with a pencil or something.
Loosen your distributor clamp enough to just be...
Yes when the engine is cold adjust choke and fast idle.
Idle adjustment when hot. Just a 1/4 turn at a time. Typical start point is 1-1/2 to 2 turns out from all the way in. But if you are already running just start turning the idle in until it starts to stumble and then come back out while...
The fast idle screw should be adjusted when you first start the engine cold. It should kick down as it warms up after kicking the throttle as it warms.
That being said you might have to adjust during the cold months vs summer months.
The idle screw should adjusted when the engine reaches...
Looking at that picture are you talking about the grooves at the top Center of the cap half bearings? What about the thrust bearing? The relief grooves on the sides? Just making sure…
I always used Clevite 77. Would you know if these bearings would be an upgrade or are they specific for high...
So we are talking about high output horsepower. I’m not sure what hp a Pro Stocker generates.
I was trying to figure exactly where they did file the groove/chamfer. There seems to be a few different ways. The pictures are a bit vague.
File across top back edge?
Just the top back edge?
So...
What kind of builds are these motors you are modifying oil thrust bearings? What application/power range are we talking about when someone should feel it necessary to do this?
I have read articles about stroker engines but don’t recall anything about extra thrust bearing protection.
Or is...
Having built my own engines in the past I found that post about drilling a hole through the thrust bearing interesting. Never heard of it.
I did some googling and found these posts about thrust bearing issues and how others have "resolved" it. Some causes they discuss too. There doesn't seem to...
...-bad crank; be careful of using the same crank chewing the thrust again. This guy chewed up three thrust bearings.
-too much end play clearance
-*bad initial start up with lack of oiling and/or with contaminants in the oil. I have witnessed youtube builders disassemble new oil pumps and saw...
I’m curious
Are you using studs for the mains instead of bolts?
If so was the block align bored with new studs? I heard that is necessary when switching out the bolts for studs.
When you say “miss” that should mean it runs on all but one cylinder? Or does it break up? Breaking up is not the same as a miss.
You can identify a misfire by using a plastic tong or if you don’t mind a possible shock by pulling one ignition wire out of the cap at a time and watch the spark...
You said the engine quit or progressively ran worse with the lights on.
You may have a bad alternator or voltage regulator. You may not be getting proper voltage.
Start the car and then pull the positive cable off the battery to see if the engine stalls. If so your charging system is bad.
If...
Electricity follows the easiest path of resistance. The suggestion of a poor ground is a good one. Make sure your engine is grounded to the frame or body. Not just a ground cable to the engine. You should have a large cable to the engine and a pigtail heavy wire from the battery cable to the...
All depends on the project and degree of restoration. I have purchased repro sheet metal. Close but not the same. They are great when there’s no access to used parts and you don’t have tools/skills to repair. The reproduction fenders and sheet are not the same gauge and fit. You can work them to...
I would hope all of the bearings and journals will be inspected. The motor is out so I would think cam,rod, main bearings should all be inspected if particles have been traveling through the engine. Wear patterns as well. Start from scratch and rule out everything.
A lot of possibilities. Was...
Just throwing some stuff out there.
I have seen main bearings installed with the wrong half in the saddle. That would cause lack of oiling.dropping the bearing cap would tell you. The motor would still run…
Are you sure it’s the thrust bearing? It could be cam bearings too. Especially if there...
